Félicien Trewey (May 23, 1848 - December 2, 1920) was born Félicien-Francois Trewey in France. At the age of fifteen Trewey ran away from home to become a magician and tight rope walker. Trewey popularised the art of Shadowgraphy and Chapeaugraphy. During his career as a magician and vaudville performer, Trewey performed all over Europe and London.

In 1871, Trewey saw Fusier give a chapeaugraphy performance, and by 1875 he was performing thirty-two to thirty-five differently shaped hats. His act was called "Twenty-Five Heads Under One Hat. Trewey would pantomime different faces of the various characters beneath the hats he created. His performances were so successful in France, Britain, America and Europe that Chapaugraphy became known by the name of Treweyism.

Trewey was a friend of the Lumières and had appeared in several of their early films, including Assiettes tournantes (Spinning Plates); Chapeaux a transformation (Hat Transformation Tricks) (1895); and Partie d'écarté (A Game of Cards). On February 20, 1896, after the building of a one thousand seat theater in England, Trewey bought the Lumiere brothers to this stage for the first presentation of Cinematograph before a paying audience.
